阅读说明：本技术 一种触点装置及电磁开关 (Contact device and electromagnetic switch ) 是由 田晓康 陈太贤 赵福高 黄广明 于 2020-03-20 设计创作，主要内容包括：本申请涉及一种电磁开关,包括驱动装置和触点装置。触点装置包括动触头组件、基体以及间隔设置于基体顶部上的两个静触头。动触头组件包括隔离件、推杆、动触头和弹性件。推杆的一端安装于驱动装置上,且另一端安装于隔离件上。动触头安装于隔离件背向推杆的一侧。弹性件夹设于隔离件和动触头之间,使得动触头在推杆的作用下实现与一对静触头接触或分离。隔离件为塑料件且位于动触头和推杆之间的外壁间隔凸设有多个凸起。如此,通过在隔离件的外壁设置类似于绝缘子结构的凸起结构,增加了材料表面爬电距离,提高了电磁开关的绝缘能力。(The present application relates to an electromagnetic switch comprising a drive means and a contact means. The contact device comprises a moving contact component, a base body and two fixed contacts arranged on the top of the base body at intervals. The moving contact component comprises an isolating piece, a push rod, a moving contact and an elastic piece. One end of the push rod is installed on the driving device, and the other end of the push rod is installed on the isolating piece. The moving contact is arranged on one side of the isolating piece, which is back to the push rod. The elastic element is clamped between the isolating element and the moving contact, so that the moving contact is contacted with or separated from the pair of fixed contacts under the action of the push rod. The isolating piece is a plastic piece and is provided with a plurality of bulges at intervals and in a protruding mode on the outer wall between the moving contact and the push rod. Therefore, the outer wall of the isolating piece is provided with the protruding structure similar to the insulator structure, the creepage distance of the surface of the material is increased, and the insulating capacity of the electromagnetic switch is improved.)
